No it isn't. Stop.

The cynical part of me says that the people who share this link with that summary are the cheaters trying to avoid getting caught, on the basis of the fact that they are patently abusing the numbers presumably because they didn't pay attention in math class.

The tests are 90% SENSITIVE. That means that of 100 AI cheaters, 10 won't be caught.

The paper you linked says the tests are 100% SPECIFIC. That means they will *never* flag a human-written paper as mostly AI.
